CROSS REFERENCE TO RELATED APPLICATION

The priority benefit under 35 U.S.C. §119(e) of U.S. Provisional PatentApplication No. 61/624,926, filed Apr. 16, 2012, is hereby claimed andthe entire disclosure thereof is incorporated herein by reference.

FIELD OF THE INVENTION

The present disclosure relates generally to water-soluble films andrelated packets. More particularly the disclosure relates to watersoluble films and packets comprised of water-soluble films coated by apowder that includes an active agent.

BACKGROUND

Water-soluble packets are known in the art. These compositions have theadvantage that they are easy to dose, handle, transport and store.

The film material used in water-soluble packets is often relativelyfragile since in most applications it must release the product quicklyand completely in water, and without leaving residue. To achieve this,the film material must be thin and must have a high water-reactivity.

The incorporation of powder into film material is known in the art. Apolyvinyl alcohol-type film can be obtained by distributing an aqueousdispersion of a fine powder on one or both sides and then drying thefilm, for example for good slip properties and adhesion resistance.

In addition, powdering of film material is known. A dusting treatmentagent for imparting inter-film lubricity to a film of thermoplasticresin has been described. In packets containing liquid compositions,powdering has been used to reduce the negative effects of weeping, suchas a tacky feel or premature loss of product. Additionally, thewater-soluble nature of such packets often renders them vulnerable tohumidity, which can weaken the structural integrity of the film.Exposure to humid conditions often results in the packets stickingtogether and packet failure upon separation.

SUMMARY

One aspect of the disclosure is a water-soluble packet comprising awater-soluble film in the form of a packet and coated by a powder,wherein the powder comprises a mixture of a powdered lubricant and anactive agent, wherein the active agent is not a fragrance. Optionally,the active agent may be encapsulated.

Another aspect of the disclosure is a water-soluble packet comprising awater-soluble film in the form of a packet and coated by a powder,wherein the powder comprises a mixture of a powdered lubricant and anactive agent which comprises a microencapsulated fragrance.

Still another aspect of the disclosure is a method of providing awater-soluble film and/or film packet additional functionality,including the steps of coating a water-soluble film and/or film packetwith a powder comprising an active agent. The water soluble packet andpowder are made according to the disclosure herein. Optionally, theactive agent can be encapsulated.

While the disclosure of preferred embodiments herein providesdescriptions of film packets, the powdered film itself, prior toformation into a packet is also contemplated, such that for anyembodiment describing a packet, a film is equally contemplated. Thus,another aspect of the disclosure is a water-soluble film coated by apowder, wherein the powder comprises a mixture of a powdered lubricantand an active agent, wherein the active agent is not a fragrance.Optionally, the active agent may be encapsulated. Another aspect of thedisclosure is a water-soluble film coated by a powder, wherein thepowder comprises a mixture of a powdered lubricant and an active agentwhich comprises a microencapsulated fragrance.

Further aspects and advantages will be apparent to those of ordinaryskill in the art from a review of the following detailed description.While the compositions and methods are susceptible of embodiments invarious forms, the description hereafter includes specific embodimentswith the understanding that the disclosure is illustrative, and is notintended to limit the invention to the specific embodiments describedherein.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows an interval plot of the numerical value (and 95% confidenceinterval) of the odor perceived from each pouch type tested according tothe Example described below.

DETAILED DESCRIPTION

Disclosed herein are water-soluble films and packets comprising awater-soluble film in the form of a packet and coated by a powder,wherein the powder comprises a mixture of a powdered lubricant and anactive agent. Optionally, the active agent is microencapsulated. In onetype of embodiment, the active agent comprises a microencapsulatedfragrance. In embodiments, the microcapsule provides for a controlledrelease of the active agent through mechanisms including, but notlimited to, mechanical rupture, melt, ablation, dissolution, diffusion,biodegradation, or pH-controlled release.

One type of embodiment of the water-soluble packets will comprise,enclosed within the packet, solid, liquid or gel compositions, orcombinations thereof. Non-limiting examples of the enclosed compositioninclude laundry detergents, bleach and laundry additives, fabric care,dishwashing, hard surface cleaning, beauty care, skin care, otherpersonal care, or food product compositions.

The disclosure further provides a method of providing additionalfunctionality to a water-soluble packet through the powder coating. Thepowder coating is comprised of a powder lubricant and an active agent.This combination has been demonstrated to be particularly advantageousin providing the packet with additional functionality while improvingthe feel of the packet surface, mitigating potential weeping of liquidproducts onto surface of the packet, and preventing the packets fromsticking together, thereby preventing possible failure duringseparation. The water-soluble packets of the disclosure herein can haveone or more other, optional advantages including, delivering an activeagent to a substrate before the water-soluble packet is dissolved,providing a controlled and delayed release of the active agent,providing an accurate dosing of active agent and enabling the packet tocomprise more than one active agent per packet. In particular,water-soluble packets according to one class of embodiments of thedisclosure can demonstrate advantageous stability if one or more of theactive agents is known to be unstable in the presence of another activeagent or in the presence of a component of the composition enclosedwithin the packet. Additionally, the method of providing the packetadditional functionality through the incorporation of the active agentinto the powder coating is advantageous because no new processingequipment is needed to produce the packet.

Ranges may be expressed herein as from “about” or “approximately” oneparticular value and/or to “about” or “approximately” another particularvalue. When such a range is expressed, another contemplated embodimentincludes from the one particular value and/or to the other particularvalue. Similarly, when particular values are expressed asapproximations, but use antecedents such as “about,” “at least,” or“less than about,” it will be understood that the particular value formsanother embodiment.

As used herein, the term “comprising” indicates the potential inclusionof other agents, elements, steps, or features, in addition to thosespecified.

As used herein and unless specified otherwise all measurements ofviscosity in centipoises (cP) are of a 4% solution at 20° C.

As used herein and unless specified otherwise, the terms “wt. %” and “wt%” are intended to refer to the composition of the identified element in“dry” (non water) parts by weight of the entire film (when applicable)or parts by weight of the entire composition enclosed within a packet(when applicable). As used herein and unless specified otherwise, theterm “phr” is intended to refer to the composition of the identifiedelement in parts per one hundred parts water-soluble polymer resin.

As used herein, the term “coating powder” refers to the mixture ofpowdered lubricant and active agent. Optionally the active agent may bemicroencapsulated.

The packet includes a water-soluble film as at least one wall of thepacket, and optionally the water-soluble film is the sole film componentof the packet. Water-soluble films of this type which can be made intopackets, optional ingredients for use therein, and methods of making thesame are well known in the art.

In one class of embodiments, the water-soluble film includes PVOH. PVOHis a synthetic resin generally prepared by the alcoholysis, usuallytermed hydrolysis or saponification, of polyvinyl acetate. Fullyhydrolyzed PVOH, wherein virtually all the acetate groups have beenconverted to alcohol groups, is a strongly hydrogen-bonded, highlycrystalline polymer which dissolves only in hot water—greater than about140° F. (60° C.). If a sufficient number of acetate groups are allowedto remain after the hydrolysis of polyvinyl acetate, the PVOH polymerthen being known as partially hydrolyzed, it is more weaklyhydrogen-bonded and less crystalline and is soluble in cold water—lessthan about 50° F. (10° C.). An intermediate cold/hot water soluble filmcan include, for example, intermediate partially-hydrolyzed PVOH (e.g.,with degrees of hydrolysis of about 94% to about 98%), and is readilysoluble only in warm water—e.g., rapid dissolution at temperatures ofabout 40° C. and greater. Both fully and partially hydrolyzed PVOH typesare commonly referred to as PVOH homopolymers although the partiallyhydrolyzed type is technically a vinyl alcohol-vinyl acetate copolymer.

The degree of hydrolysis of the PVOH included in the water-soluble filmsof the present disclosure can be about 75% to about 99%, for example. Asthe degree of hydrolysis is reduced, a film made from the resin willhave reduced mechanical strength but faster solubility at temperaturesbelow about 20° C. As the degree of hydrolysis increases, a film madefrom the resin will tend to be mechanically stronger and thethermoformability will tend to decrease. The degree of hydrolysis of thePVOH can be chosen such that the water-solubility of the resin istemperature dependent, and thus the solubility of a film made from theresin, and additional ingredients is also influenced. In one class ofembodiments the film is cold water-soluble. A cold water-soluble film,soluble in water at a temperature of less than 10° C., can include PVOHwith a degree of hydrolysis in a range of about 75% to about 90%, or ina range of about 80% to about 90%, or in a range of about 85% to about90%. In another class of embodiments the film is hot water-soluble. Ahot water-soluble film, soluble in water at a temperature of at leastabout 60° C., can include PVOH with a degree of hydrolysis of at leastabout 98%.

Other film-forming resins for use in addition to or in an alternative toPVOH can include, but are not limited to, modified polyvinyl alcohols,polyacrylates, water-soluble acrylate copolymers, polyaminopropylsulfonic acid and salts thereof, polyitaconic acid and salts thereof,polyacryamides, polyvinyl pyrrolidone, pullulan, cellulosics, includingbut not limited to carboxymethyl cellulose and hydroxypropyl methylcellulose, water-soluble natural polymers including, but not limited to,guar gum, xanthan gum, carrageenan, and starch, water-soluble polymerderivatives including, but not limited to, modified starches, includingethoxylated starch and hydroxypropylated starch, poly(sodiumacrylamido-2-methylpropane sulfonate), polymonomethylmaleate and saltsthereof, copolymers thereof, and combinations of any of the foregoingwith each other and/or with PVOH.

The water-soluble resin can be included in the water-soluble film in anysuitable amount, for example an amount in a range of about 35 wt % toabout 90 wt %. The weight ratio of the amount of the water-soluble resinas compared to the combined amount of additives can be any suitableratio, for example a ratio in a range of about 0.5 to about 5, or about1 to 3, or about 1 to 2.

Water-soluble resins for use in the films described herein (including,but not limited to PVOH resins) can be characterized by any suitableviscosity for the desired film properties, optionally a viscosity in arange of about 8.0 to about 40.0 cP, or about 10.0 cP to about 30 cP, orabout 13 cP to about 27 cP. The viscosity of a PVOH resin is determinedby measuring a freshly made solution using a Brookfield LV typeviscometer with UL adapter as described in British Standard EN ISO15023-2:2006 Annex E Brookfield Test method. It is internationalpractice to state the viscosity of 4% aqueous solution at 20° C. Allviscosities specified herein in cP should be understood to refer to theviscosity of 4% aqueous solution at 20° C., unless specified otherwise.

It is well known in the art that the viscosity of a resin is correlatedwith the weight average molecular weight (Mw) of the same resin, andoften the viscosity is used as a proxy for Mw. Thus, the weight averagemolecular weight of the water-soluble resin optionally can be in a rangeof about 35,000 to about 205,000, or about 80,000 to about 170,000, orabout 97,000 to about 160,000 Daltons. The molecular weight of the resinneed only be sufficient to enable it to be molded by suitable techniquesto form a thin plastic film.

The water-soluble films according to the present disclosure may includeother optional additive ingredients including, but not limited to,plasticizers, surfactants, emulsifiers, fillers, extenders, antiblockingagents, detackifying agents, antifoams, film formers and otherfunctional ingredients, for example in amounts suitable for theirintended purpose.

Water is recognized as a very efficient plasticizer for PVOH and otherpolymers; however, the volatility of water makes its utility limitedsince polymer films need to have at least some resistance (robustness)to a variety of ambient conditions including low and high relativehumidity. Glycerin is much less volatile than water and has been wellestablished as an effective plasticizer for PVOH and other polymers.Glycerin or other such liquid plasticizers by themselves can causesurface “sweating” and greasiness if the level used in the filmformulation is too high. This can lead to problems in a film such asunacceptable feel to the hand of the consumer and even blocking of thefilm on the roll or in stacks of sheets if the sweating is not mitigatedin some manner, such as powdering of the surface. This could becharacterized as over plasticization. However, if too little plasticizeris added to the film the film may lack sufficient ductility andflexibility for many end uses, for example to be converted into a finaluse format such as packets.

Plasticizers for use in water-soluble films of the present disclosureinclude, but are not limited to, sorbitol, glycerol, diglycerol,propylene glycol, ethylene glycol, diethyleneglycol, triethylene glycol,tetraethyleneglycol, polyethylene glycols up to MW 400, 2 methyl 1, 3propane diol, lactic acid, monoacetin, triacetin, triethyl citrate,1,3-butanediol, trimethylolpropane (TMP), polyether triol, andcombinations thereof. As less plasticizer is used, the film can becomemore brittle, whereas as more plasticizer is used the film can losetensile strength. Plasticizers can be included in the water-solublefilms in an amount in a range of about 25 phr to about 50 phr, or fromabout 30 phr to about 45 phr, or from about 32 phr to about 42 phr, forexample.

Surfactants for use in water-soluble films are well known in the art.Optionally, surfactants are included to aid in the dispersion of theresin solution upon casting. Suitable surfactants for water-solublefilms of the present disclosure include, but are not limited to, dialkylsulfosuccinates, lactylated fatty acid esters of glycerol and propyleneglycol, lactylic esters of fatty acids, sodium alkyl sulfates,polysorbate 20, polysorbate 60, polysorbate 65, polysorbate 80, alkylpolyethylene glycol ethers, lecithin, acetylated fatty acid esters ofglycerol and propylene glycol, sodium lauryl sulfate, acetylated estersof fatty acids, myristyl dimethylamine oxide, trimethyl tallow alkylammonium chloride, quaternary ammonium compounds, salts thereof andcombinations of any of the forgoing. Too little surfactant can sometimesresult in a film having holes, whereas too much surfactant can result inthe film having a greasy or oily feel from excess surfactant present onthe surface of the film. Thus, surfactants can be included in thewater-soluble films in an amount of less than about 2 phr, for exampleless than about 1 phr, or less than about 0.5 phr, for example.

One type of secondary component contemplated for use is a defoamer.Defoamers can aid in coalescing of foam bubbles. Suitable defoamers foruse in water-soluble films according to the present disclosure include,but are not limited to, hydrophobic silicas, for example silicon dioxideor fumed silica in fine particle sizes, including Foam Blast® defoamersavailable from Emerald Performance Materials, including Foam Blast® 327,Foam Blast® UVD, Foam Blast® 163, Foam Blast® 269, Foam Blast® 338, FoamBlast® 290, Foam Blast® 332, Foam Blast® 349, Foam Blast® 550 and FoamBlast® 339, which are proprietary, non-mineral oil defoamers. Inembodiments, defoamers can be used in an amount of 0.5 phr, or less, forexample, 0.05 phr, 0.04 phr, 0.03 phr, 0.02 phr, or 0.01 phr.

Processes for making water-soluble articles, including films andpackets, include casting, blow-molding, extrusion and blown extrusion,as known in the art. One contemplated class of embodiments ischaracterized by the water-soluble film described herein being formed bycasting, for example, by admixing the ingredients described herein withwater to create an aqueous mixture, for example a solution withoptionally dispersed solids, applying the mixture to a surface, anddrying off water to create a film. Similarly, other compositions can beformed by drying the mixture while it is confined in a desired shape.

The film is useful for creating a packet to contain a composition, forexample laundry or dishwashing compositions, thereby forming a packet.The film described herein can also be used to make a packet with two ormore compartments made of the same film or in combination with films ofother polymeric materials. Additional films can, for example, beobtained by casting, blow-molding, extrusion or blown extrusion of thesame or a different polymeric material, as known in the art. In one typeof embodiment, the polymers, copolymers or derivatives thereof suitablefor use as the additional film are selected from polyvinyl alcohols,polyvinyl pyrrolidone, polyalkylene oxides, polyacrylic acid, cellulose,cellulose ethers, cellulose esters, cellulose amides, polyvinylacetates, polycarboxylic acids and salts, polyaminoacids or peptides,polyamides, polyacrylamide, copolymers of maleic/acrylic acids,polysaccharides including starch and gelatin, natural gums including,but not limited to, xanthan, and carrageenans. For example, polymers canbe selected from polyacrylates and water-soluble acrylate copolymers,methylcellulose, carboxymethylcellulose sodium, dextrin, ethylcellulose,hydroxyethyl cellulose, hydroxypropyl methylcellulose, maltodextrin,polymethacrylates, and combinations thereof, or selected from polyvinylalcohols, polyvinyl alcohol copolymers and hydroxypropyl methylcellulose (HPMC), and combinations thereof.

The packets of the present disclosure comprise at least one sealedcompartment. Thus the packets may comprise a single compartment ormultiple compartments. In embodiments comprising multiple compartments,each compartment may contain identical and/or different compositions. Inturn, the compositions may take any suitable form including, but notlimited to liquid, solid and combinations thereof (e.g. a solidsuspended in a liquid). In some embodiments, the packets comprises afirst, second and third compartment, each of which respectively containsa different first, second and third composition. In some embodiments,the compositions may be visually distinct as described in EuropeanPatent Application Number 09161692.0 (filed Jun. 2, 2009 and assigned tothe Procter & Gamble Company).

The compartments of multi-compartment packets may be of the same ordifferent size(s) and/or volume(s). The compartments of the presentmulti-compartment packets can be separate or conjoined in any suitablemanner. In some embodiments, the second and/or third and/or subsequentcompartments are superimposed on the first compartment. In oneembodiment, the third compartment may be superimposed on the secondcompartment, which is in turn superimposed on the first compartment in asandwich configuration. Alternatively the second and third compartmentsmay be superimposed on the first compartment. However it is also equallyenvisaged that the first, second and optionally third and subsequentcompartments may be attached to one another in a side by siderelationship. The compartments may be packed in a string, eachcompartment being individually separable by a perforation line. Henceeach compartment may be individually torn-off from the remainder of thestring by the end-user,

In some embodiments, multi-compartment packets include threecompartments consisting of a large first compartment and two smallercompartments. The second and third smaller compartments are superimposedon the first larger compartment. The size and geometry of thecompartments are chosen such that this arrangement is achievable. Thegeometry of the compartments may be the same or different. In someembodiments the second and optionally third compartment each has adifferent geometry and shape as compared to the first compartment. Inthese embodiments, the second and optionally third compartments arearranged in a design on the first compartment. The design may bedecorative, educative, or illustrative, for example to illustrate aconcept or instruction, and/or used to indicate origin of the product.In some embodiments, the first compartment is the largest compartmenthaving two large faces sealed around the perimeter, and the secondcompartment is smaller covering less than about 75%, or less than about50% of the surface area of one face of the first compartment. Inembodiments in which there is a third compartment, the aforementionedstructure may be the same but the second and third compartments coverless than about 60%, or less than about 50%, or less than about 45% ofthe surface area of one face of the first compartment.

The packets of the present disclosure may comprise one or more differentfilms. For example, in single compartment embodiments, the packet may bemade from one wall that is folded onto itself and sealed at the edges,or alternatively, two walls that are sealed together at the edges. Inmultiple compartment embodiments, the packet may be made from one ormore films such that any given packet compartment may comprise wallsmade from a single film or multiple films having differing compositions.In one embodiment, a multi-compartment packet comprises at least threewalls: an outer upper wall; an outer lower wall; and a partitioningwall. The outer upper wall and the outer lower wall are generallyopposing and form the exterior of the packet. The partitioning wall isinterior to the packet and is secured to the generally opposing outerwalls along a seal line. The partitioning wall separates the interior ofthe multi-compartment packet into at least a first compartment and asecond compartment. In one class of embodiments, the partitioning wallmay be the only enzyme containing film thereby minimizing the exposureof the consumer to the enzymes.

Packets may be made using any suitable equipment and method. Forexample, single compartment packets may be made using vertical formfilling, horizontal form filling, or rotary drum filling techniquescommonly known in the art. Such processes may be either continuous orintermittent. The film may be dampened, and/or heated to increase themalleability thereof. The method may also involve the use of a vacuum todraw the film into a suitable mold. The vacuum drawing the film into themold can be applied for about 0.2 to about 5 seconds, or about 0.3 toabout 3, or about 0.5 to about 1.5 seconds, once the film is on thehorizontal portion of the surface. This vacuum can be such that itprovides an under-pressure in a range of 10 mbar to 1000 mbar, or in arange of 100 mbar to 600 mbar, for example.

The molds, in which packets may be made, can have any shape, length,width and depth, depending on the required dimensions of the packets.The molds may also vary in size and shape from one to another, ifdesirable. For example, the volume of the final packets may be about 5ml to about 300 ml, or about 10 to 150 ml, or about 20 to about 100 ml,and that the mold sizes are adjusted accordingly.

In one embodiment, the packet includes a first and a second sealedcompartment. The second compartment is in a generally superposedrelationship with the first sealed compartment such that the secondsealed compartment and the first sealed compartment share a partitioningwall interior to the packet.

In one embodiment, the packet including a first and a second compartmentfurther includes a third sealed compartment. The third sealedcompartment is in a generally superposed relationship with the firstsealed compartment such that the third sealed compartment and the firstsealed compartment share a partitioning wall interior to the packet.

In various embodiments, the first composition and the second compositionare selected from one of the following combinations: liquid, liquid;liquid, powder; powder, powder; and powder, liquid.

In various embodiments, the first, second and third compositions areselected from one of the following combinations: solid, liquid, liquidand liquid, liquid, liquid.

In one embodiment, the single compartment or plurality of sealedcompartments contains a composition. The plurality of compartments mayeach contain the same or a different composition. The composition isselected from a liquid, solid or combination thereof.

Heat can be applied to the film in the process commonly known asthermoforming. The heat may be applied using any suitable means. Forexample, the film may be heated directly by passing it under a heatingelement or through hot air, prior to feeding it onto a surface or onceon a surface. Alternatively, it may be heated indirectly, for example byheating the surface or applying a hot item onto the film. The film canbe heated using an infrared light. The film may be heated to atemperature of at least 50° C., for example about 50 to about 150° C.,about 50 to about 120° C., about 60 to about 130° C., about 70 to about120° C., or about 60 to about 90° C.

Alternatively, the film can be wetted by any suitable means, for exampledirectly by spraying a wetting agent (including water, a solution of thefilm composition, a plasticizer for the film composition, or anycombination of the foregoing) onto the film, prior to feeding it ontothe surface or once on the surface, or indirectly by wetting the surfaceor by applying a wet item onto the film.

Once a film has been heated and/or wetted, it may be drawn into anappropriate mold, preferably using a vacuum. The film can bethermoformed with a draw ratio of at least about 1.5, for example, andoptionally up to a draw ratio of 2, for example. The filling of themolded film can be accomplished by utilizing any suitable means. In someembodiments, the most preferred method will depend on the product formand required speed of filling. In some embodiments, the molded film isfilled by in-line filling techniques. The filled, open packets are thenclosed forming the packets, using a second film, by any suitable method.This may be accomplished while in horizontal position and in continuous,constant motion. The closing may be accomplished by continuously feedinga second film, for example, a water-soluble film, over and onto the openpackets and then sealing the first and second film together, typicallyin the area between the molds and thus between the packets.

Any suitable method of sealing the packet and/or the individualcompartments thereof may be utilized. Non-limiting examples of suchmeans include heat sealing, solvent welding, solvent or wet sealing, andcombinations thereof. The water-soluble packet and/or the individualcompartments thereof can be heat sealed at a temperature of at least200° F. (93° C.), for example in a range of about 220° F. (about 105°C.) to about 290° F. (about 145° C.), or about 230° F. (about 110° C.)to about 280° F. (about 140° C.). Typically, only the area which is toform the seal is treated with heat or solvent. The heat or solvent canbe applied by any method, typically on the closing material, andtypically only on the areas which are to form the seal. If solvent orwet sealing or welding is used, heat may optionally also be applied.Suitable wet or solvent sealing/welding methods include selectivelyapplying solvent onto the area between the molds, or on the closingmaterial, by for example, spraying or printing this onto these areas,and then applying pressure onto these areas, to form the seal. Sealingrolls and belts as described above (optionally also providing heat) canbe used, for example.

The formed packets may then be cut by a cutting device. Cutting can beaccomplished using any known method. It may be preferred that thecutting is also done in continuous manner, and preferably with constantspeed and preferably while in horizontal position. The cutting devicecan, for example, be a sharp item, or a hot item, or a laser, whereby inthe latter cases, the hot item or laser ‘burns’ through the film/sealingarea.

The different compartments of a multi-compartment packets may be madetogether in a side-by-side style wherein the resulting, cojoined packetsmay or may not be separated by cutting. Alternatively, the compartmentscan be made separately.

In some embodiments, packets may be made according to a processincluding the steps of:

-   -   a) forming a first compartment (as described above);    -   b) forming a recess within some or all of the closed compartment        formed in step (a), to generate a second molded compartment        superposed above the first compartment;    -   c) filling and closing the second compartments by means of a        third film;    -   d) sealing the first, second and third films; and    -   e) cutting the films to produce a multi-compartment packet.

The recess formed in step (b) may be achieved by applying a vacuum tothe compartment prepared in step (a).

In some embodiments, second, and/or third compartment(s) can be made ina separate step and then combined with the first compartment asdescribed in European Patent Application Number 08101442.5 or WO2009/152031 (filed Jun. 13, 2008 and assigned to the Procter & GambleCompany).

In other embodiments, packets may be made according to a processincluding the steps of:

-   -   a) forming a first compartment, optionally using heat and/or        vacuum, using a first film on a first forming machine;    -   b) filling the first compartment with a first composition;    -   c) on a second forming machine, deforming a second film,        optionally using heat and vacuum, to make a second and        optionally third molded compartment;    -   d) filling the second and optionally third compartments;    -   e) sealing the second and optionally third compartment using a        third film;    -   f) placing the sealed second and optionally third compartments        onto the first compartment;    -   g) sealing the first, second and optionally third compartments;        and    -   h) cutting the films to produce a multi-compartment packet.

The first and second forming machines may be selected based on theirsuitability to perform the above process. In some embodiments, the firstforming machine can be a horizontal forming machine, and the secondforming machine can be a rotary drum forming machine, optionally locatedabove the first forming machine.

It should be understood that by the use of appropriate feed stations, itmay be possible to manufacture multi-compartment packets incorporating anumber of different or distinctive compositions and/or different ordistinctive liquid, gel or paste compositions.

The water-soluble film and/or packet described herein must be at leastpartially coated with a powder composition. The powder can be present onthe packet in an amount of at least about 0.01 mg/cm², or in a range ofabout 0.01 mg/cm² to about 10 mg/cm², for example. The outer surface ofthe film packet can be coated. In some embodiments, the inner surface ofthe film packet can be coated, in the alternative to or in addition tothe outer film surface. In one embodiment, the powder composition isapplied to the film after forming a packet. In another embodiment, thepowder composition is applied to the film before forming a packet.

The powdered lubricant is a powder that when present as the only powdercomponent aids in preventing the packets from sticking together duringconditions which can be present during film conversion, or when packetsare in close proximity, such as in secondary packaging, preventingpossible failure during separation, optionally one or more of thefollowing: temperature about 10° C. to about 40° C., or about 15° C. toabout 35° C., or about 20° C. to about 25° C.; relative humidity fromabout 10% to about 50%, or about 15% to about 45%, or about 20% to about40%, or +/−5% relative humidity of the equilibrium percent relativehumidity (eRH) of the film as received in its package. Additionally, inone class of embodiments the powdered lubricant can mitigate potentialweeping of liquid contents and thereby improve the feel of the packetsurface. When present in the coating powder composition in an amount ofat least about 1 wt %, for example, the powdered lubricant additionallyacts as a carrier for active agent and aids in uniformly dispersing theactive agent. In some embodiments, the powdered lubricant aids in themechanical rupture of the microcapsules that contain active agents.

In one type of embodiment, the powdered lubricant has an averageparticle size of at least about 0.1 μm, or in a range of about 0.1 μm toabout 100 μm, for example. Typically, a powder such as starch could beused, such a powder being well known. Other suitable materials includemodified starches (including, but not limited to, corn starch, potatostarch, or hydroxyl ethyl starch), silicas, siloxanes, calciumcarbonate, magnesium carbonate, clay, talc, silicic acid, kaolin,gypsum, zeolites, cylclodextrins, calcium stearate, zinc stearate,alumina, magnesium stearate, alumina, zinc oxide and combinations of anyof the foregoing. Generally, the powder will be inert. The powderlubricant is present in the coating powder in an amount of at leastabout 1 wt %, or in a range of about 1 wt % to about 99 wt %.

The active agent, when present in the coating powder composition in anamount of at least about 1 wt %, or in a range of about 1 wt % to about99 wt %, provides additional functionality to the packet. Inembodiments, the active agent can comprise one or more componentsincluding, but not limited to, enzymes, oils, flavors, colorants, odorabsorbers, fragrances, pesticides, fertilizers, activators, acidcatalysts, metal catalysts, ion scavengers, bleaches, bleach components,fabric softeners or combinations thereof. The active agent can take anydesired form, including as a solid, a liquid, a mull, a paste, a gas,etc., and optionally can be encapsulated.

In certain embodiments, the active agent may comprise an enzyme.Suitable enzymes include enzymes categorized in any one of the sixconventional Enzyme Commission (EC) categories, i.e., theoxidoreductases of EC 1 (which catalyze oxidation/reduction reactions),the transferases of EC 2 (which transfer a functional group, e.g., amethyl or phosphate group), the hydrolases of EC 3 (which catalyze thehydrolysis of various bonds), the lyases of EC 4 (which cleave variousbonds by means other than hydrolysis and oxidation), the isomerases ofEC 5 (which catalyze isomerization changes within a molecule) and theligases of EC 6 (which join two molecules with covalent bonds). Examplesof such enzymes include dehydrogenases and oxidases in EC 1,transaminases and kinases in EC 2, lipases, cellulases, amylases,mannanases, and peptidases (a.k.a. proteases or proteolytic enzymes) inEC 3, decarboxylases in EC 4, isomerases and mutases in EC 5 andsynthetases and synthases of EC 6.

The powdered lubricant can be prepared as a master batch. The coatingpowder composition can be prepared by combining a portion of thepowdered lubricant master batch with the active agent to form a daughterbatch of coating powder. This process can be continuous or intermittent.A continuous feed of active agent can be comprised of multiple activeagent compositions added sequentially, for example, to a feed ofpowdered lubricant.

The coating powder composition can be applied to the film or packet byany suitable means. In a one embodiment, one or more stationary powderspray guns are used to direct the powder stream towards the packets,from one or more than one direction, while the packets are transportedthrough the coating zone by means of a belt conveyor. In an alternativeembodiment, the pouch is conveyed through a suspension of the coatingpowder in air. In yet another alternative embodiment the packets aretumble-mixed with the coating powder in a trough-like apparatus. Inanother embodiment, which can be combined with any other embodiment,electrostatic forces are employed to enhance the attraction between thepowder and the packet. This type of process is typically based onnegatively charging the powder particles and directing these chargedparticles to the grounded packets. In other alternative embodiments, thepowder is applied to the packet by a secondary transferring toolincluding, but not limited to rotating brushes which are in contact withthe powder or by powdered gloves which can transfer the powder from acontainer to the packet. In yet another embodiment the powder is appliedby dissolving or suspending the powder in a non-aqueous solvent which isthen atomized and sprayed onto the packet.

In one class of embodiments, the powder is applied to the packet in anaccurate dose. This class of embodiments utilizes closed-system drylubricant application machinery, such as PekuTECH's powder applicator PM700 D. In this process the coating powder, optionally batch-wise orcontinuously, is fed to a feed trough of application machinery. Thepackets are transferred from the output belt of a standard rotary drumpouch machine onto a conveyor belt of the powder application machine,wherein a controlled dosage of the functionalized coating powder isapplied to the packet. The packet is thereafter conveyed to a suitablesecondary packaging process.

In some embodiments, in use the microcapsule will be mechanicallyruptured thereby releasing the active agent. Suitable active agents tobe released via mechanical rupture include, but are not limited to,fragrances, oils, enzymes, odor absorbers, and activators. In oneembodiment, a fragrance will be microencapsulated, providing acontrolled and efficient delivery mechanism. In this embodiment, thepacket will retain the fragrance until the point of use, upon whichhandling by the consumer will mechanically rupture some of themicrocapsules, releasing the fragrance. This embodiment is advantageousin mitigating the inherent “malodor” of the water-soluble film itself,or from a component of the material packaged in the water-soluble film,in the presence of the consumer.

In alternative embodiments, in use the active agent will be releasedfrom the microcapsule by dissolution of the microcapsule. Suitableactive agents to be released upon microcapsule dissolution include, butare not limited to, flavors, colorants, bleaches, bleach components,enzymes, activators, acid catalysts, metal catalysts, and ionscavengers. In one embodiment, the water-soluble packet may be comprisedof edible water-soluble film. The microencapsulation of a flavor activeor other active agent, for example, allows for the use of ingredientsthat are not or might not be compatible with the water-soluble film. Forexample, an ingredient may cause crosslinking or other reactions thatwould adversely affect the film solubility. The encapsulation of theflavor therefore allows for the inclusion of the ingredient. In otherembodiments the encapsulation of both a flavor and a color would allowfor an enhanced flavor experience and an aesthetically pleasing visualappearance. In one type embodiment, an edible, hot water-soluble filmmay contain a plain, uncolored oatmeal composition. In theseembodiments, upon dissolution of the microcapsule, the color and flavorcan be imparted to the plain, uncolored oatmeal composition, forexample, red and strawberry, blue and blueberry, or brown and maple.Applying the color/flavor microcapsules via the coating powder alsoadvantageously streamlines the manufacturing process and makes for amore flexible supply management, allowing the manufacturer tomass-package a single type of composition, i.e., plain oatmeal, in awater-soluble film and add the color/flavor at a later time.

In one class of embodiments, the active agent will be released from themicrocapsule by diffusion. Suitable active agents for use with adiffusion release mechanism include, but are not limited to, pesticidesand fragrances. In one embodiment the water-soluble packet can contain alaundry composition and the coating powder can comprise a perfume. Inthis embodiment, the fragrance will slowly diffuse from the microcapsuleduring storage, advantageous in mitigating the inherent “malodor” of thewater-soluble film itself, or from a component of the material packagedin the water-soluble film, in the presence of the consumer, and willalso release the remaining fragrance on the laundry substrates duringthe wash cycle.

Embodiments may comprise an ablation or erosion mechanism for therelease of active agents from the microcapsules. Suitable active agentsto be released upon ablation of the microcapsules include, but are notlimited to, bleaches, bleach components, and enzymes. In one embodiment,the composition enclosed in the water-soluble packet may comprise apercarbonate bleaching agent and the microencapsulated active agent maycomprise the bleach activator TAED. In this embodiment, upon ablation,the microcapsule will release the TAED, allowing it to react with thepercarbonate, forming an activated bleach.

In alternative embodiments, the active agent will be released uponbiodegradation of the microcapsule. Suitable active agents for use in abiodegradable microcapsule include, but are not limited to, pesticidesand fertilizers. In one embodiment, a water-soluble packet may contain afertilizer or other lawn-care composition. The packet can be dusted witha biodegradable microcapsule containing a pesticide. After application,the microcapsule will biodegrade, releasing the pesticide. In thisembodiment, the consumer can safely use a single dose of pesticidewithout coming in direct contact with the pesticide.

In some embodiments, the microcapsules will release the active agentupon melting. Suitable active agents to be released when themicrocapsule melts include, but are not limited to, fabric softeners. Inone embodiment, the active agent may comprise a fabric softener. Thefabric softener would be delivered to a laundry substrate via awater-soluble packet comprising a detergent enclosed within the packet.During the wash cycle, the microcapsules would disperse onto the laundrysubstrate, however the fabric softener would not be released until thesubstrate was heated to a temperature not encountered in the clotheswasher (e.g. greater than 40° C. or greater than 50° C., or greater than55° C., or greater than 60° C.) but only encountered in the dryer.

In another type of embodiment, the microcapsule will release the activeagent upon dry brittle failure. For example, in one embodiment theactive agent can include a fabric softener. The fabric softener would bedelivered to a laundry substrate via a water-soluble packet comprising adetergent enclosed within the packet. During the wash cycle, themicrocapsules would disperse onto the laundry substrate, however thefabric softener would not be released until the capsules were driedsufficiently to become brittle and crack, thus releasing their contents.For example, the microcapsules can be designed to become brittle at acritical relative humidity significantly below standard householdconditions, e.g. <40%, or <40%, or <35%, or <35%, or <30%, or <30%, or<25%, or <25%.

Embodiments may comprise pH triggered release of the active agent fromthe microcapsule. Suitable active agents for a pH triggered release mayinclude, but are not limited to, fragrances, oils, enzymes, odorabsorbers, and activators. In one embodiment the composition enclosed inthe water-soluble packet may comprise a laundry detergent compositionand a first enzyme that is unstable in the presence of a protease, andthe active agent may comprise a protease enzyme. The packet, when placedin a washing machine would dissolve, releasing the detergent compositionand the first enzyme. When the washing water pH is adjusted toappropriate levels the microcapsule would release the protease, therebyallowing a full dose of a first enzyme and a protease to reach a stainedsubstrate. In an alternative embodiment, a protease may be enclosedwithin the packet and the active agent may comprise a second enzymeencapsulated in a microcapsule, wherein the protease would be releasedfirst and upon reaching the appropriate pH, the second enzyme would bereleased. In yet another embodiment, the composition enclosed within thepacket may comprise a first enzyme and the active agent may comprise asecond enzyme, wherein both the first and second enzyme are unstable inthe presence of the other. In another embodiment, the packet can containan automatic dishwasher detergent and the microcapsule can contain arinse aid, wherein the microcapsule is insoluble in highly alkalinesolutions (e.g., pH greater than 9.3, or greater than 10) and soluble inneutral to mildly alkaline conditions, such that the rinse aid is notreleased during the wash cycle but only in the rinse cycle.

EXAMPLES Effect of Microencapsulated Fragrances on Pouch Malodor

The effect of a powder coating comprising a starch powdered lubricantand a perfume microcapsule active agent on pouch malodor was evaluated.In this example, malodor was imparted to scent-free pouches to representmalodor that might be produced from a water-soluble film or componentspackaged within water-soluble films during storage. The pouches werecoated with a powder comprising a powdered lubricant (starch) and anactive agent (perfumed microcapsules) and the effect of the perfumemicrocapsules were determined by evaluation by a sensory panel. Fivetypes of pouches were evaluated, including: non-coated, malodor-freepouches (designated “blank”); starch coated, malodor-free pouches(designated “only starch”); starch coated, malodor pouches (designated“malodor+starch”); and pouches treated with malodor and coated with astarch/perfume microcapsules(PMC) powder at two concentrations, 25% ofstarch by weight (designated “malodor+starch+PMC”) and 50% of starch byweight (designated “malodor+starch+PMC 2X”).

The pouches evaluated were 0.6 fl. oz. Triple Action Purex® Ultrapacks(Free and Clear) manufactured by The Dial Corporation (Scottsdale,Ariz.). Pouches were packaged in stand-up bags (18 pouches/bag) withdimensions of 185 mm×210 mm. The volume of the bags was 2.2 L withoutthe pouches, headspace in the bag with the pouches was found to be 1.9L. The “blank” pouches were used as received. Pouches were treated withmalodor by dropping into the stand-up bags, cotton balls infused with200 μl of an aqueous (deionized water) tert-butanethiol (TBT) solutionhaving a TBT concentration of 300 μl/l. The starch or starch andperfumed microcapsule mixture were then added to the pouches.

The starch carrier powder used was a 28 μm foodgrade starch-basedprinting press powder. The “starch only” and the “malodor+starch”pouches were coated with the carrier powder by adding 0.25 g of starchto stand-up bags containing malodor-free pouches and malodor-treatedpouches, respectively. The bags were sealed using zip seal fitments onthe individual bags and were stored overnight.

The perfume microcapsules used were melamine formaldehyde capsules witha perfume oil in the core. The mean diameter of the capsules was 18 μm.The perfume microcapsules were obtained as a slurry in water; the slurrywas spray-dried using a dual fluid melt spray prior to incorporation ofthe microcapsules into the starch carrier powder. The dried perfumemicrocapsules were combined with the starch prior to introduction tostand-up bags containing malodor treated pouches. A measure of 0.0625 gof dried perfume microcapsules was added to 0.25 g of starch and themixture was added to stand-up bags of malodor-treated pouches to formthe “malodor+starch+PMC” pouches. A double measure (0.125 g) of driedperfume microcapsules was added to 0.25 g of starch and the mixtureadded to stand-up bags of malodor-treated pouches to form the“malodor+starch+PMC 2X” pouches. The bags were sealed using zip sealfitments on the individual bags and were stored overnight.

Fourteen panelists were given the sample bags with random numbering andasked to evaluate the odor from the headspace of the bags on a scale ofvery bad to very good (very bad, bad, slightly bad, neutral, slightlygood, good, very good). The responses were given a numerical value from1 (very bad) to 7 (very good).

FIG. 1 shows the interval plot of the numerical value (and 95%confidence interval) of the odor perceived from each pouch type. The“blank” and “only starch” samples were not perceived to be significantlydifferent from each other by the sensory panel. The “Malodor+starch” wasperceived significantly below the no-effect value of 4, with the meanand the 95% confidence interval below 4. All of the pouches treated withthe perfume microcapsule/starch mixture (“malodor+starch+PMC” and“malodor+starch+PMC 2X”) showed positive effects on the panelists withmean values and 95% confidence intervals significantly higher than theno-effect value of 4. The odor perceived at 50% perfume microcapsuleloading was slightly better than the odor perceived at 25% perfumemicrocapsule loading. Thus, the Example demonstrates that thefunctionalized powder is able to overcome malodor.
